Greetings,
 
As always, I'm puzzled  and stuck . . .
 
Does anyone have any  catalog, dated from 1894 thru about 1900, that has 
Steinheil Orthostigmat  lenses in it?
 
The Orthostigmat name  didn't appear until late-1893, and I have catalog 
listings after  1900.
 
Every now and then it would be nice  to crack open a lens and find what you 
were expecting to see.   But naturally, the lens I have doesn't match anything 
in  the reference material that I've got.
 
I know, I know . . .  haven't we just done this?  Yes, but that's how it 
goes.   It's like having to mow the lawn every other (insert f-word here) day,  
it's just another of those cycle-of-life things.  What? you guys  don't have to 
mow your lawns every (insert f-word here) other (insert  another f-word here) 
day?  Don't get me started on lawns, life, suburbia,  futility, neighbors 
dogs, the stupid - stupid! - weather, etc.  Where was  I . . . ???
 
The problem is that the engraving  says Weitwinkel Aplanat  which would make 
it a wide angle RR type lens -  but, of course, it turns out not to be an 
RR-type lens.  Has  cemented triplets, instead of cemented pairs.
 
Who else has either  Weitwinkel Aplanats or Orthostigmat lenses?  Getting 
them open and  apart is relatively easy with basic household tools and a bit of  
leverage.  If they survive, getting them back together more-or-less  properly 
isn't hard at all.
 
For the curious, the  lens and the various puzzlements can be seen at:
